10 Deadliest Enemies Of The Stargate Universe
8. Jaffa
For thousands of years, the Goa'uld System Lords spread fear and death across the Milky Way through its primary military force comprised entirely of a race of people called the Jaffa. The Jaffa are an offshoot of humanity that was genetically engineered by the Goa'uld to serve as a slave race.
They were engineered without an immune system, but in its place existed an abdominal pouch, where they could incubate a larval Goa'uld symbiote. The larval Goa'uld worked in the place of the missing immune system, but it also enhances their strength, longevity, and immunity to infections and poison.
These enhancements made the Jaffa the deadliest warriors in the galaxy, and for millennia, they were instrumental in conquering every planet they descended upon. The Jaffa were fanatical in their devotion to their gods and would fight for them to their dying breath.
Ultimately, the Jaffa revolted against the Goa'uld, with people like Teal'c leading the way. He did so by declaring that "The Jaffa are the foundation upon which the false gods have built their empires. We can tear them down!" In the end, that's what they did, but the Jaffa remain a powerful force in the galaxy even without their Goa'uld masters pulling their strings.
